A coolant coalescer is designed to run continuously on an individual sump to help prevent the growth of bacteria by removing tramp oil and aerating the coolant.

The coalescer works by bringing dirty coolant in through the intake attachment to the filter cartridge. The filter cartridge removes chips and oil droplets which are manually discharged. Clean coolant is returned to the sump from the bottom of the coalescer.


  • Extends coolant life
  • Reduces coolant usage
  • Reduces rancidity and related problems such as dermatitis, misting

Belt skimmers

Belt skimmers use a stainless steel or poly belt which is lowered into the coolant mixture. The belt moves through wiper blades that remove the oil from both sides of the liquid as it passes through the unit. The oil is then captured in a collection container.


  • Easy to install
  • Can remove up to 1 litre of tramp oil per hour
  • Ability to fit in small or shallow sumps
  • Variety of belt lengths from 60cm to 3m foot drop (custom sizes available)

Proportioning Pumps

A proportioning pump is designed to assist with the mixing of coolants with water. The mixer accurately mixes fluid at a wide variety of concentrations.


  • Ensure properly mixed fluid
  • Easy to use and install
  • Controls concentration -- minimizes concentrate usage
  • Reduces time & labour required to manually mix fluids

Disk skimmers

Disk skimmers use a disk that rotates through the metalworking fluid or cleaner. The tramp is removed from the disc by a wiper system.

The oil passes through the unit and is placed in a collection container. Disk skimmers function best when a significant proportion of the surface area is immersed in the fluid.


  • Heavy oil loads (up to 22 litres per hour)
  • Capable of handling elevated fluid temperatures
  • Continuous duty
  • Rugged construction
  • Easy to install


A refractometer is a precision optical device designed to measure the concentration or mixture ratio of water soluble fluids. It helps determine the correct concentration of your metalworking fluid which helps optimises its performance.

Chem Arrow offers both traditional handheld refractometers and digital refractometers.


  • Easy to operate
  • Very portable
  • Helps control product usage
  • Minimizes overall operating costs

FinCoater Applicator System for Fin Stamping (HVAC)

The Chem Arrow FinCoater is designed to control the amount of lube that is applied to both the top and bottom of the fin stock. The FinCoater is the ideal roller coater to apply a very light coating of lubricant to thin gauge material as it enters the fin press.

The unit is computer controlled to dispense the correct amount of lubricant to the material on each stroke of the press. There are two sets of rollers, one set to stabilise fin stock and one set to apply the lubricant.

FinCoater Applicator Advantages

  • Lubricant usage reduction of at least 25% up to 50%
  • Lubrication Application Control improvements compared to lubricant bath
  • EH&S employee improvements
    • Operator area cleanliness improvement
    • Risk reduction for operator incidents due to cleanliness improvements
    • Operator has less risk of lubricant contact
      • No lubricant mist from applicator
  • Less risk of product packaging becoming wet due to lubricant run off from the coils due to lubricant over application
  • Lower lubricant cost that would justify the applicator return on investment in less than 2 years
